IntroductionABB’s comprehensive family of low voltage dry type transformers (LVDTT) provide long life, quiet, and reliable operation.

Type QL are ABB’s large power transformers ranging from 15 kVA to 1000 kVA. The QL transformers come in standard NEMA 2 enclosures with rain shield kits available for NEMA 3R installations. Stainless steel enclosures are available as options as well. QL transformers are available in single or Three-phase configurations with either aluminum or copper windings. Type QL’s are DOE 2016 compliant with models available for Canadian NRCan efficiency standards.

All of the LVDTTs through 1,000 kVA are UL listed under the requirements of Standard 5085 and/or 1561. In addition, each transformer meets the requirements of NEMA T-20-2014.

General purpose transformers are rated 600 Volts and below for supplying appliances, lighting, and power loads from electrical distribution systems. Standard distribution voltages are 600, 480, and 240 Volts; standard load voltages are 480, 277, 240, 208, and 120 Volts. The transformer is used to obtain the load voltage from the distribution voltage while providing galvanic isolation. Since no vaults are required for installation, these transformers can be located right at the load to provide the correct voltage for the application. This eliminates the need for long, costly, low voltage feeders.

Construction – Type QLLarge power transformersQL units come standard enclosed in a NEMA 2 drip-proof painted metal enclosure with natural draft ventilation. The core-and-coil assembly is mounted on rubber isolation pads to reduce noise generated by transformer vibration. Rain shield kits are available for conversion to a NEMA 3R enclosure suitable for outdoor service. Type QL transformers are UL Listed: XQNX:E79145; XQNX7:E79145; XQNX2:E79145 or XQNX8:E79145.

NEMA enclosure ratingsType QL transformers are standard as NEMA 2 painted steel enclosures. NEMA 3R or NEMA 3R stainless steel (316) enclosures are available up to 150 kVA. NEMA 3R includes the rain shield kit (also 316 SS).

To specify a stainless-steel enclosure for an aluminum wound transformer, substitute the letter “S” in the fifth character of the ABB product number. For example, 9T10A1004 changes to 9T10S1004. For copper wound transformers substitute the letter “Z” in the fifth character of the ABB product number. For example, 9T10C1004 changes to 9T10Z1004. All QL model product numbers begin with 9T1, 9T6, 9T7 and 9T8.

Transformer tapsTransformer taps compensate for high or low line (supply) voltages. FCAN (full capacity above nominal) and FCBN (full capacity below nominal) are standard on Type QL transformers rated 15 kVA through 300 kVA and with a primary voltage of 240 V or higher. These have a total of six available voltage taps – four 2.5% taps (FCBN) below the nominal tap and two 2.5% taps above (FCAN) the nominal tap. This arrangement provides a 15% range of tap voltage adjustment. Transformers rated 500 kVA and higher have four available voltage taps – two 2.5% taps above (FCAN) the nominal tap and two 2.5% taps below (FCBN) the nominal tap.

Sound levelsAll general purpose transformers are as quiet, or quieter than required by NEMA ST-20. Average sound levels are warranted not to exceed the values listed for each load rating shown in the below table. Sound characteristics vary between transformers of identical voltage and kVA rating. The range of variation may be 4 to 8 decibels.

These values apply only to specified test conditions because the characteristic of the installation can cause them to be higher under operating conditions. Where acoustical noise is deemed to be of concern, proper steps should be taken during installation to minimize audible noise transmission. Please refer to the installation manual for installation and operation recommended practices to minimize the audible sound of the transformer.

If lower sound levels are needed or desired, -3 dB and -5 dB options are available for most models.

All ABB Type QL (80 °C, 115 °C and 150 °C) DOE and NRCan compliant transformers use 220 °C insulation systems and meet all applicable NEMA, ANSI, UL, and IEEE dry type transformer standards.

The design life of transformers that have different insulation systems is the same, since the allowable temperature rise of an insulation material system is predicated on a specified life for all insulation. The lower temperature systems are designed for the same life as higher temperature systems.

Key to the chart• All assume 40 °C ambient temperature.• Coil temperature rating (Temp Rise) is a typical

specification when choosing a transformer• The Hot Spot is the buffer added for internal hot spots• For large power transformers, an 80 °C temp rise will

cost more than a 150 °C, and will likely last longer• Designing for other ambient temperatures like

50 °C for use in desert regions will increase the cost• Lower coil temp rise = higher price• Higher ambient temp requirement = higher price

Type QL insulation system• Insulation Class: 220 °C, UL recognized insulation system

with a maximum of 150, 115 or 80 °C rise above 40 °C ambient temperature

• Temperature rise ratings are in accordance with UL 1561• All ABB Type QL dry type transformers use a 220 °C

Product descriptionK-factor is a standardized way to indicate the ability of a transformer to withstand harmonics. These units shall not exceed rated winding temperature rise at full load and rated K-factor. Neutrals and lugs are capable of handling 200% of rated secondary phase current.

Full-width copper electrostatic shielding is standard on all ABB K-factor rated transformers. Effective coupling ca-pacitance is 30 pf. Common mode noise attenuation averag-es 120 dB, and transverse mode noise attenuation averages 30 dB.

ApplicationsFor commercial applications with significant nonlinear electronic loading, use K=4 for systems with 50% connected nonlinear electronic loads; K=13 for systems with 100% connected nonlinear electronic loads.

Higher K-factor rated units are available for unique applications.

Product descriptionThese low noise transformers are designed to operate at re-duced noise levels. The vibrations within the magnetic steel core have been greatly reduced, thus lowering the humming of the transformer 3 dB less than NEMA/ANSI standards. Available in Aluminum or Copper windings, with either a 150°C, 115°C or 80°C rise.

ApplicationsType QL low noise transformers are ideal when quiet opera-tion is required such as near offices, in school buildings, or hospitals. Although they are inherently quieter, installation can greatly influence their noise level and therefore care should be taken in following acoustical principles as well as proper installation procedures. Closets and corners should be avoided as they act as megaphones by seemingly increas-ing noise levels.

Guard III™ Harmonic Mitigating Transformers help eliminate harmonics, improve power quality, and help save energy by reducing the energy (heating) losses. They maintain DOE 2016 energy efficiency even when harmonics are present. Power supplies that convert AC to DC current – for plant floor equipment, computers, copiers, electronic ballasts, and others – generate harmonics that create an irregular current waveform. These harmonics, in turn, create power quality problems such as overheated transformers, motors and neutral wires; nuisance breaker trips; and electronic equipment malfunction and failure.

Key features - 0° Phase shift; +15° Phase Shift; -15° Phase Shift or -30° Phase Shift - Copper windings - K-factor load profile of 20 - Crest factor load profile of 5 - NEMA 1 and/or 2 drip-proof enclosure - Rain shield available for field conversion to NEMA 3R - NEMA 3R stainless steel (Type 316) up through 150 kVA


Product descriptionThis easily installed and serviceable unit incorporates a Type QMS transformer (single-phase) or a Type QL transformer (three-phase), a primary main circuit breaker, a secondary main circuit breaker, and a load-center-design breaker panel. Since these components don’t have to be installed and interconnected separately, the contractor or user can reduce installation time and costs. Because of the single-unit concept, only one, handy Servicenter™ needs to be mounted.

Available in single-phase, 5 through 25 kVA, and in three-phase, 15 through 30 kVA, 600 Volt class ratings, the ABB Servicenter™ is a convenient, economical way to meet your industrial and temporary power requirements.

The transformer—The Servicenter™ utilizes ABB transformer design which has twenty years of field-proven experience behind it and a long track record for assuring consistent, reliable performance. Type QMS transformers employ a 180°C UL Recognized insulation system with a 115°C rise. Type QL transformers employ a 220°C UL Recognized insulation system with a 150°C rise.

The panel—The panel assembly includes the rugged ABBPowerMark Plus™ circuit breaker load center interior, E-frame primary breakers, and E-frame or Q Line secondary breakers. The load center will accept one-, two-, or three-pole (three-phase) common trip circuit breakers and ground fault breakers. All Servicenters™ come equipped with the properly sized primary main and secondary main circuit breakers installed and prewired. Branch breakers are not included.

Advantages

ABB Type QL midtapped transformer enables the user to transform three-phase power from 480 Volts primary to 240 Volts secondary and have 120 Volt, reduced capacity tap (RCT) single-phase capability as well. This is because a single-phase midtap is brought out of one coil of the unit’s three-phase secondary winding. These transformers are UL listed, File E-79145.

ApplicationThe Type QL midtapped design can be used wherever there is 480 Volt, three-phase supply available and the load is primarily 240 Volt three-phase with a nominal amount of 120 Volt, single-phase power required. Normally, in this instance, a small single-phase as well as a three-phase transformer would be required to provide the necessary transformation.

Caution: When utilizing the 120 Volt midtap for single-phase applications, the single-phase load should not exceed 5 percent of the three-phase kVA rating. The three-phase kVA load must be reduced by the same percentage as that added by the single-phase load. Additional loading beyond 5 percent may cause the transformer to overheat and fail. If the single-phase load is in excess of 5 percent, it is recommended that a separate single-phase unit be used to handle the load.

ApplicationThe use of SCR control circuitry with adjustable-speed drives has resulted in a need for a line of isolation transformers specifically designed to meet the demanding requirements of SCR drives. Symmetrically placed taps and added coil bracing minimize mechanical forces caused by the often severe SCR drive duty cycles. These features also help protect the transformer from the regenerative duty and more frequent short-circuits associated with SCR drives.

—Drive isolationAluminumThree-phase

Isolation transformers also reduce line-pollution feedback resulting from SCR firing circuits. The ABB delta-wye designs meet the NEC requirements for grounded secondary neutrals that isolate primary distribution systems. kVA ratings of the DIT line cover most dc motor requirements from 3 to 1000 hp.

Enclosed drive isolation transformers are UL listed.
